| BERMAD Mining Mining COMBINATION AIR VALVE Model MN-C30 BERMAD C30 is a high quality combination air valve for a variety of pipe networks and operating conditions. It evacuates air during pipeline filling, allows efficient release of air pockets from pressurized pipes, and enables large volume air intake in the event of network draining. With its advanced aerodynamic design, double orifice and Surge Protection device (optional), this valve provides excellent protection against air accumulation and prevents vacuum formation, with improved sealing in low pressure conditions. Features and Benefits Straight flow body with large diameter automatic orifice: Higher than usual flow rates. Aerodynamic full-body kinetic shield: Prevents premature closing, without disturbing air intake or discharge. Dynamic sealing: Prevents leakage under low pressure conditions (1.5 psi; 0.1 bar). The boss on the base can be tapped with a thread for pressure gauge connection, check point or test drain for air valve function. Threaded Side outlet (2”; DN50) for connection of Surge Protection (code SP) or Inflow prevention (code IP) devices. Compact, simple and reliable structure with fully corrosionresistant internal parts; lower maintenance and increased life span. Design in compliance with functional standard and water service standards. Factory approval and Quality Control: Performance and specification tested and measured with specialized test bench, including vacuum pressure conditions. Additional Features & Accesories Surge Protection (code SP) device: Smoother operation, preventing damage to the valve and the system. Inflow Prevention (code IP) device: Prevents intake of atmospheric air in cases where this could lead to damaged pumps, required re-priming, or disruption of siphons. Service Ports fitted: ¹/8”;DN3 or ¼”;DN6 plug for pressure gauge connection, check point or test drain for air valve function. Extension with downwards outlet, only for inlet sizes 2-3”; DN50-80.

Pipe networks: Protection against air accumulation and vacuum formation. Inside leaching modules at lateral pies. In proximity to control valves and flowmeters: Prevention of inaccurate pressure regulation and biased readings due to air existence in t
